Abstract: A programmable multi-channel automatic control system is disclosed. A user-accessible front panel is prorammed by the insertion of program pins into program time slots that correspond to one hour increments of a 24 hour day. Two detent positions of the program slot enable the user to select two distinct on/off schedules for each of the individual program channels. Seven-day program slots for each individual program channel are provided to allow selected equipment to operate on alternate schedules and/or to remain on or off for complete 24 hour periods.
